Black-throated Sparrows (Amphispiza bilineata) are common breeding birds throughout the desert regions of North America and can be considered nest-site generalists. Information about how spatial (e.g., vegetation) and temporal factors influence [...]

Populations of Bachman's Sparrows (Peucaea aestivalis) have declined range-wide since the late 1960s. Populations at the periphery of their range have exhibited some of the steepest declines, and these sparrows are now rare or extirpated over mu[...]
